Divide contacts on android. Is it possible to use two phone numbers on the same SIM card? How to delete duplicate contacts on Android

Question: " Judging by the settings and descriptions of the last two of my phones, several numbers can be prescribed to one sim card (well, two at least). Well, this is a free interpretation of the fact that the phone can communicate more than one line at the same time (even with one number, I use it for 5 years), and in addition to the line number, you can set the phone number on this line. Explain the people? ;) And then an attempt to contact the CSO with a question causes children's bewilderment from the other end of the phone."

Short answer

There are several ways to use several phone numbers, Taste one machine / SIM card, but there is no standard for this and everything, in general, depends on the goodwill of the operator.

Long answer

It may seem strange, but even when creating standards mobile communications The third generation of the needs of subscribers who need phones with several numbers were not taken into account. And this is despite the fact that users need such an opportunity, it has long been known to everyone, and nevertheless - WHO and now there.

Why? Suppose that there is a standard, working always and everywhere way to combine multiple mobile numbers in one SIM card. Now we think about - what mobile operator It will be drawn to the fact that he "divides" a SIM card with an account of the second mobile numberwhich can be done belongs to a completely different operator.

EDAK may turn out that the subscriber will begin to compare tariffs, services, quality of the coating, and there, you look, and will go to competitors. Disorder? Disorder.

Now add a number of purely technical problems to this: for example, the phone will have to maintain work at two different frequencies at the same time - after all, if the numbers are from different operators, then frequencies of broadcast channels basic stations They will also be different at any point. And if the numbers from one operator? Even in this case, everything is not smooth - a whole range of GSM network processes includes a search in the HLR-E of a unique identifier (IMSI) SIM card by phone number, and the standard HLR allows you to assign only one telephone number of the telephony service specific SIM card . In addition, according to the standard there is no way to specify which phone number is used with outgoing calls.

In the amount, all this leads to the fact that solutions that allow the subscriber to have two numbers exist, but (with rare exceptions) have half functionality:

• Or only one number of two works, and the subscriber can choose - which one
• Or work both numbers, but they must belong to one operator. At the same time, the solution is often working only within the network of this operator and does not work in roaming.

What decisions are it?

Solutions that do not really decide

If the operator allows you to assign to "Telephony", "Data Transfer", "Fax" three different numbers to services (who said "UMC"?), The subscriber can receive calls (ordinary, data and faxes) on any of these three numbers. True, with outgoing calls, the number assigned to the "Telephony" service will always be used. Cons are obvious - the solution is suitable only to those who want to use alternative numbers only for incoming calls.

Solutions from phone manufacturers

Certain models of phones allow you to use two telephone numbers with one (special) SIM cardAt the same time, the phone provides the user with the ability to choose exactly which number "is substituted" with outgoing calls, and incoming calls and SMS are delivered to both numbers.

However, a little phone with a cunning firmware is not enough - such functionality requires support from the operator. In particular, his HLR-s should be able to store two phone numbers for network Services "Voice", "Data Transfer", "Fax" and implement on both numbers.

Some time ago there was an attempt to turn this solution (called ALS, Alternate Line Service) to a part of the GSM standard, but the Committee rejected the proposed changes on the basis that they are tied to specific iron producers (for example, Nokia) and specific operators (for example , Orange in UK).

Apparently, the author of the issue stumbled upon this functionality. If you have Nokia with a firmware that supports ALS, you can try to click and hold the "#" key. The phone should write something like "Line 2 Selected" and you will lose the ability to make and make incoming calls until you click "#" again :)

In general, the whole, this decision has almost been almost evoked. There are no operators on the SIS expanses that supported it.

Programmable multisim cards allow you to record several pairs on them (IMSI, Ki) and, thus, a SIM card that can make a set of identifiers in the process during the process. True, there is a snag - it is impossible to easily take and "merge" data from two standard SIM cards to a programmable disc. The reason is that the secret key (ki) cannot be considered from the standard SIM card, and you can only try to select it, and that is only if the A38 algorithm used in the map is known selected. In addition, the selection of Ki, built into the majority of SIM cards, can be irreversible to block it, and you for some time (until you change the SIM) generally lose your ability to use the appropriate phone number.

Solutions from manufacturers in-platforms

If the operator's network is poured, it can implement the solution described at the very beginning of the story in its network, but not tied to a specific manufacturer of phones.

To begin with, the operator (as already mentioned) will need to change all its HLRs so that several phone numbers can be stored in them for one SIM card. Then the operator needs to implement a special IN-service, which will be remembered (stored in the database on the side of the operator), which of the subscriber's numbers is currently "active", and what - "Additional", and provide the Subscriber with the opportunity to choose an active number - through voice (IVR) Menu, via USSD request.

After that, the operator must configure its network (or accounts of all subscribers) so that all incoming and outgoing calls of all subscribers are processed by the in-platform, which will check: 1) whether the subscriber has a service "MULTILINE"; 2) what number should be substituted with outgoing call Or to which number at the moment you need to deliver calls and SMS-s. According to the results of Invisors in in will be "on the go" to change (if necessary) phone numbers in signaling information, which will create a complete illusion of two simultaneously working independent numbers. In the case of supporting both parties with the functionality of "CAP Roaming", the solution will work even in networks of other operators.

However, and here it was not without a spoon of tar: first, all traffic will need to "wrap" through the in-platform. If it is not designed for such loads - then the operator will need to invest in the upgrade (and this is despite the fact that the service is not a cash, but working on the image) or to put up with a deterioration in the quality of communication. Secondly, this solution is badly getting along with any other in-services.

After all, if the Multiline service is needed that the trigger worked on any outgoing call and there was a control on IN, and the prepaid service needs the same, it turns out that either the implementation of these services should know about each other and be content with one trigger for two, or arises The need to organize the so-called double triggering, which, if I'm not mistaken, is impossible according to the standard at all. And even if the specific manufacturer of in-platforms and HLRs and allows you to organize a double triggering, provided that it is possible to use it only in the operator's network, it is still bad and leads to a significant increase in the number of signal traffic and therefore - to a larger network load.

SummaryIf I really want, you can provide two numbers with one (or two) SIM cards, but this in any case is associated with problems and restrictions.

Sometimes the phone creates two or more copies of one contact. This happens mainly when restarting the device, synchronization of contacts or shift the SIM card and random synchronization of all contacts.

It can greatly clutch and make it difficult to navigate through contacts. If you have duplicate contacts on the Android smartphone, you can get confused which one is correct. Perhaps you can even send a message to the outdated number.

Are you looking for an easy way to combine duplicate contacts? Do not worry, in my section of the tips and secrets, I will show you several ways to remove duplicates.

Combining contacts in the phone

Most Android phones have a built-in contact combining feature. The phone scans all contacts and removes all duplicated with similar rooms and address. email. In MIUI, you will find this option in the Contacts application.

For this discover Contacts → Long Pressing the Menu button → Advanced → Duplicate Association .

Combining contacts in google-contacts

If you saved contacts in Google contacts, you can easily combine them by entering your Google account. To do this after logging into the system, you just need to go to the menu and select in the left sidebar - Similar contacts .

You will see the number of duplicate contacts. In the list shown, you can choose the contacts that need to be combined or click on " Combine everything«.

Contact contact with third-party applications

The two above-mentioned methods are simple and affordable, one of them is in smartphones by default, and the second is Google. If you do not have a thousand contacts and hundreds of duplicates, they are perfect for you.

But there is another way - this third-party applications, in Play Market you'll find great amount free applications To combine contacts.

How do you find and remove duplicate contacts?

SummaryIf I really want, you can provide two numbers with one (or two) SIM cards, but this in any case is associated with problems and restrictions.

You use Android, you have a lot of friends, and the address book reminds just a chaotic list. You downloaded and installed your contacts in the account settings, indicated the address Facebook, Twitter and Skype, and in the address book they all appeared: Petro, Petro, Peter and everything in such a spirit. You see that one and the same contact is presented in different ways. And you want to know that your contact writes to you from all accounts at the same time - for example, a message via Facebook or Skype call.

By combining contacts, you can clean up in the address book

Collect all contacts.

For those who do not know how to collect together contacts to your Android smartphoneYou need to make a number of simple actions.

First action you activate Google Account. You do this when you first turn on Internet services, you automatically activate Google Talk. Note You can use several Google Accounts, such as Personal Gmail and Working Google Apps. With your domain. For input google account Apps You specify your full email.

Many have a Vkontakte profile. it social network Number one for all CIS users - Ukraine, Russia and neighboring countries. To work in it you need to download a small program of VKontakte Sync, link to download the program download VKontakte Sync . After installing the program proceed Settings Choose Accounts and synchronization We prescribe your credentials in VKontakte. Put Tits background synchronization We update accounts.

Facebook. this profile It is default. You can enter Facebook data, you can skip. If you activate, you will receive updates among your friends, in particular - photos, update statuses and comments to news and links. This feature is available for each contact in the sections of the event and media. And in all sorts of widgets you will see generalized information. To answer the response, install Facebook application.

Twitter. Malopular, but rapidly gaining her client who integrates with many news services and allows you to quickly share news and read news from the news portals you are interested in. Each subscriber receives the so-called short message tape, headers. You can add Twitter accounts with built-in default client.

Skype. A program known as a unique way to conduct online voice calls and video calls, without paying the conversation time between subscribers of one program. You only use the Internet of your smartphone - Wi-Fi, or EDGE / 3G. When you turn on the program, you can synchronize accounts directly from skype. To make calls the GPRS channel not enough

You can also find third-party clients Synchronization and other services.

Total we get a whole mass of the contacts that you will have in the address book.

We combine all contacts.

Please note that each contact is assigned the surname and name. It picks up from Vkontakte, and from Facebook, and cannot be changed. The same name will be automatically combined, which will partly simplify our task. But if the contact is recorded by Latin, and the other Cyrillic, the auto attitude can fail. The second reason for the failure of the auto access may be variations of Slavic names - Sasha and Alexander, Vasya and Vasily, etc. Such names do not merge.

• To connect one contact with the other - choose it, and click on the associated contacts field.
• Then select similar contacts in the dialog box.
• In case of incomprehension of fields - surnames, name, mail, numbers - click below all contacts and looking for the desired scrolling
• Click on such contact
• All you have tied up account

You can associate in one contact together up to 5 accounts.
